Bi-Directional HL-7 Order Communication Interface
Ensure that the integrity of medication orders is maintained in multiple systems, each allowing modifications to the orders.
- Defined and implemented appropriate messages and rules necessary to maintain order consistency between physician order entry, pharmacy, and medication charting applications.
CTS worked with clinicians and technical staff to define proper HL-7 order message sequences necessary to maintain the proper state of orders between systems. Detailed sequence diagrams were constructed to capture this design and to serve as the blueprint for implementation. COM+ was used to implement business logic and to maintain the integrity of orders using appropriate transaction management techniques. These interfaces were tested rigorously to verify their integrity under common and infrequent scenarios.
